hydrocarbon based gas detection sensor using optical fiber and apparatus using the same

摘要

The present invention relates to an optical fiber type hydrocarbon-based gas detection sensor and a gas detection device using the same, wherein the gas detection sensor has a substrate, a clad layer surrounding a core layer has a polishing portion partially polished along a longitudinal direction, and the polishing portion is a substrate A reaction installed to be exposed to the hydrocarbon-based gas to be detected by being formed with titanium dioxide on the upper surface of the substrate including the side polished optical fiber that is bently inserted and coupled to the substrate to be exposed to the upper surface of the side polished optical fiber and the polished portion of the side polished optical fiber Have wealth. According to such an optical fiber type hydrocarbon-based gas detection sensor and a gas detection device using the same, it provides an advantage of providing high detection sensitivity for a hydrocarbon-based gas.
